The Vpresent invention relates to improvements in packing devices and the primary lobject is to provide a novel and improved packing device which enables bags, and especially box bags, to be packed With a varietyy of articles While the is'contained in a holder ot appropriate size and shape which acts as a mold or former, after which the top of the bag Which is .exposedV above the mold may be easily andquickly closed, as by folding the top flaps, following which the bag is pushedv upwardly or out of the mold While a length of gummed tape is stretched over the top and pressed against opposite sides ot thebag to secure or seal it. Heretofore it has been the general custom of department and other stores to pack various articles and goods in cartons which Were made of paper board or yother rela-y tively heavy material to enable them to retain their form during packing ment, such practice being followed especially when thev goods Were intended 'for shipment'- by parcels-post or similar transportation, but such practice has been eX# pensive, owing to the relatively highcost ot the cartons and thefamount ot labor involved in packing and closing or sealing them. The present inventionenabl-es relatively inexpensive paper bags to be enr ployed instead of the cartons heretofore used, and it enables such bags to be packed While held in proper form by a mold, and they operations oi closing the bag. and the application oli ay securing oi sealing strip thereto are facilitated.

To these and other ends the invention consists in certain improvements and coinbinations and arrangements of parts, all as will be hereinafter more fully described, the features of novelty being pointed out par-A ticularly in the claims at the end of the specification. y I

is shown in Fig. Y 1 by screws on. the plate EZ',

and will be hereinafter described invdetail, but it is to be understood that the' invention is not restricted to the precise construction shown as equivalent constructions are contemplated, and suchl will be included within the scope of the claims. Y In the present instance, the packing device comprises a support 1 the top of a table side of which is mounted a plate,which may be rectangular in form, as 6, is secured to the support 3 Vwhich entend throughl its corners. A. mold or former l of appropriate size and shape is adapted to'be ino'untev the plate and providing a chamber or pocket 5 iny which the bag to be packed `is placed. The plate 2 andthe mold l are preferably constructed from sheet metal of suitable kind and thickness, the upper and lowerV edges ofthe mold being preferably whenthese levers are' swung Vformed with out-turned flanges erably, a pair of clamping or (5 and 7 to stiffen it so that it' will retain its sliape, the upper flange also providing a rounded edge which the partV of the Abag projecting above it may engage and *dousv avoid' cutting or tearing of the bag. The lower flange 7 at oppositesides of the -mold. isutilized means for securing'the mold iinniovably ip positionV on the supporting Vplate .Q j Preilocking levers 8 are provided, each being pivoted on a pin or bolt 9 whichA mayl entend periphery of the mold, the portionsa lo these-levers being arranged to move into a position'above andto bear on the flange about their 4and pivots, thereby clamping' holding the mold against the. supporting plate. lreferably, aV strip 1() is riveted or otherwise securedto the 'opposite lower edges of the mold,they being 'shown applied and riveted to the underside. of the flange 7, and these strips areV sufficiently wide to project inwardly and thusl form ledges 11 which are "adapted to provide a support for a follower plate 12 when the latter is iii its lowerniost position,v the follower plate 12 u supported firmly at its edges, so that it will provide a suitable support against which the articles or contents may be packed in the bag. This follower plate preferably conx forms substantially to the size and shape o from Fig.

to the operation of 'removthe mold incident j from the mold and restoring a packedl bag ing the packing bes'- Y j The supporting plate i2 is provided with means for accurately supporting the mold or former thereon. Preferably, and as shown,

the supporting plate is provided with rows of steel or other which may be' or stand on the upper plate 2. This 'which may lodge on it projecting upwardly from '18, the levers 8 as a through thev 'plate' f2, inA theA margin thereof beyond theY n changeable with the mold shown in Figures 1 `and 5, is illustrated in ln this instance,

being thus v device to lreceive another ineens? of mold positioning and supporting buttons 13, lil, 15, and 16 which may be composed hard material and upwardly from the surface of the plate, theA tops of these buttons all lying in the saine' plane. tioned that the strips 10 of the mold will register with and rest thereon, vand are for the purpose of suporting the mold above the supporting plate in order'toA avoid interference with the proper positioning of the other packing material the supporting plate mold by excelsior or or lie beneaththe mold and to avoid interference with the proper placing of another mold which may be interchanged forY one previously used. Y Y' Y v Means is provided for registering or insuring proper positioning the supporting plate, such means consisting preferably ofdowely pins 17 which project upwardly above the plane buttons and are arranged to enter apertures 18 of corresponding size in the lower flange. 7 of the mold.v f W hen the mold is placedon the buttons on the support'ingfplateso that the dewel pins register are swung outwardly, as

shown in Figures 11 and andthe mold is then secured iiiiinovably to the' supporting plate. Y

Vlvlolds or forniers of different dimensions may be provided in order to adapt the devicev to the packing of bags of different sizes and shapes. One of such molds', which is inter- Figures 8 and 9. the body of the mold desig`- nated er is shorter Vand narrower than the mold shown' in Figures 1 and 5. The bot-V ends of the mold. Also the strip 1Ua is correspondingly extended so that it willfbear project These rows of buttons are so posi- Y of the mold on 1 of the tops ofthe Y d with kthe apertures f on the pins 15 and 16, and'also lthepins 13' and 11i. Theextensions onthe ends of this mold are sufficient to bring them in position to be engaged and clamped by the securing devices. Reinforcing webs 19 may be provided between the body ofthe mold and the end extensions thereof to insure a follower plate 19xor different dimensions,

.dimensions will be upwardly projecting flaps or closing means,

In using'ni'olds of a different size 105 toni flange *7L is extended at the Opposite l after the packingL of lthe bag has been completed, are folded or'closed after which the bag and itscontentsare pushed upwardly and thusejected from the mold, and during this operation a gunnned strip maybe held by the hands of the operator so thatthe strip will be stretched across vthe closed top of the bag and its ends'brought into pasted relation with the opposite sides of the bag, this strip serving to secure or seal the flaps or closure.l

Different means may be provided .for

side of the follower plate 12. The headV 22 is of such thickness that it will be ac# commodated in the space left between the follower plate 12 and the supporting plate 2 when the follower plate is in its lower-most position, at which time its ends rest on the ledges ll which project inwardly from the strips l0. The plunger 2O is preferably raised to perform itsy bag ejecting function in consequence of the depression of a pedal. Different means may be employed to effect this result, the means employed for this purpose `in the present instance comprising a pair of vertically movable rack bars 23 which are guided to reciprocate in a vertical guide or housing 24, the upper end of which may be xed to the under side of the supporting plate 2 by the screws 25 or other suitable means. The lower ends of these rack bars are operatively connected to a treadle which may be in the form of the stirrup 26 shown.

The opposite sides of the plunger 2O are provided with rack teeth 27, 28 having journals 29 which are mounted to revolve freely in the guide or housing 24 are interposed between the plunger 20 and the racks 23 and mesh with the teeth thereon. In such a construction, when the plunger 20 is in its normal or lowermost position, as is shown in F ig. l, the racks 23 will be in their raised position, as shown in that figure and. the treadle or stirrup will be elevated. Tension springs 3() stretched between the treadle and the supporting plate 2 may be used to return the treadle and rack bars to their elevated position and to retain them in such position until pressure is applied to the treadle. When the treadle is depressed the descent o f the rack b ars 23 in consequence thereof will cause rotatlon of thepinions 28 in directions to cause as- `30, will cause the sizes or heights.

Vcome to rest and the pin and pinions cent of the plunger'20,the head 22 onthe latter then acting on vthe follower plate 12 to push the packed or filled bag .upwardly and lthus eject it from the. mold, and ascent of the treadle andthe rack bars'conne'cted thereto, through the actionof thesp-rings pinions to operate vto ,re tract or lower the plunger. '1 y pEach mold or formerispreferably made sufficiently deep to enable it' tov be utilized in the packing of bags ofdiiferent vertical When a bagofy shallowerdepthy than 4that of the mold .is to be '-packed,- the follower plate l2 and lthe plunger may be limited in their descentY so that they "do" not recede to the bottom of the mold,`but will be supported at an appropriate distance above the bottom of the mold to providera space in the mold above the 'follower plate of v a' depthI corresponding with o f the bag to' 1lie-packed.` For this purpose,

the guide or casing 24 may be provided with a number of suitably graduated apertures 31 to receive a pini32,fandwhenthis pin is inserted into one of these apertures, it

extends through the vguide or casing and is ina position to act as an abutment against which the lower end of `the vplunger will willfthereby limit the depth of the bag-'receiving'cavity in the moldly i the: depth Figure 10 shows a box., bag packed, closed and secured or sealed with the aidA of the packing device. Such bags, when open or extended, have a body at` which is substantially rect-angular in lboth transverse? andy longitudinal cross-section, the "bottoni of the bag b is flat'v or mouth of the bag is adapted to be closed by flaps .c which project upwardly from* the four vertical sides of the bag? `and* are slit at the corners thereof so that these flaps are foldableinwardly one upon-the otherv to form a substantial-ly' flat top or closure.y "fl represents a length of a gummed or ad'- hesive strip which is stretched yacross the closed top of the bag and has its endseX tended downwardly along and pastedv against oppesite ve'rtical'sides of the bag. p rIhe operation of a packing device enr-f bodying the present invention is substantially as follows While the treadle is invite" normal'elevated position/and the plunger 20 and follower plate 12 are in their lower-1 most position, as, forexample, isV shown' in Fig. l, the bag isV expanded or opened'and placed in the mold so that its bottom` rests on the plate Vl2-and its Vflaps wardly beyond the topv of the mold.A 'The' articles to be packed are then placed iny the bag. These articles maybe of 'various-kinds such as those sold and shipped by `depara ment and other stores. In the packing/ofA bottles or other fragile articles e'Xcelsiorr-'or other packing material is packed around the.

substantially' so, and the project upi completed, the mouth mold To add further security articles ,and the spreading tendency of the bag' under the packing operationis sustained i by theA side walls? oi' the mold and the follower plate 12,7so that tearing or breaking of the bag is avoided and the packed'bag is molded into the shapedetermined by the for thel conf tents of the bag, the bag maybe of the duplex type; that is, one bag contained within another bag toA afford a double thickness.

`After the packing of the bagr hasbeen thereof which projects above the mold Vis closed, as byfoldng site sides ofthe ascending bag,

'been done, the operator 'and afterr this has depresses Vthe pedal by the.v foot in consequence of which the plunger 2O 'operates to force the l,plate 12 upwardly, thereby pushing the packed bag upwardly and out of the mold. VVhilethis ejectin'g operation is taking place, Vthe operator stretches .a length of. gummed strip across the top of the bag andV presses the ends of the gummed strip against the oppo`- inwardly the top flaps,

closure of the bag is secured or sealed. This mode of operation enables the operator to apply the `gummedfstrip across the top olV the bagwhilethe `flaps are held in Vclosed position and to effect the aiiixing 'of the ends of the gummed strip vto the sides of the Abag withoutthe necessity of releasing the hands fromthe bag, and, hence, the closing and securing or sealing of the bag may be accomplished with speed and facility'. soon as one 'bag isejected from the mold, vthe treadle is allowed to rise, thus lowering the plunger 20 and plate 12 to their initial pod sitionso that the mold may receive l'another bag ready for packing.
